We are aiming to use one of the ready made PHP applications of billing and making invoices with most of the features that we require but need customisation. If you are ready to do few before we start the project please contact us.
Some features it miss:
Template for the bill
Same bills alerts
Also support after delivery is important to us. If you are available and professional in PHP please let us discuss and send sample of earlier work
Support on uploading the project to hosting and make it work in any device
